1 Claim.

This invention relates to improvements in multiple shot water pistols.'An important object of the invention is to provide water pistols of thetype referred to, with simple and practical means for effecting thedischarge of a jet of water by the mere pressure upon a trigger. Therelease of the trigger permits expansion of a flexible, expansible softrubber cylinder, which is provided with a suitable valve and is incommunication with a second cylinder having a valve arranged to beclosed when the valve in the first mentioned cylinder is opened uponcollapse of said cylinder, and vice versa. These, and other importantobjects of the invention are accomplished by the construction shown anddescribed in the accompanying drawing, in which:

Figure 1 is a sectional side view of the pistol;

Figure 2 is an end elevation of the pistol from the muzzle end thereoflooking toward the rear;

Figure 3 is a plan view of the pistol;

Figure 4 is a side view of the double collapsible valve and tubing;

Figure 5 is a view of the front end of the front collapsible valve; and

Figure 6 is a View of the front end of the rear collapsible valve.

The mechanism for pumping fluid from the reservoir 6 and for ejectingthe fluid through the muzzle 4 of the pistol consists of a pair of softrubber cylinder chambers 8 and 9 arranged coaxially with respect to oneanother and positioned within the muzzle 4 of the pistol. Thecylindrical chamber 8 has a closed forward end in which there ispositioned a horizontal slit 12. A rubber tube 1 is secured within thecylindrical chamber and is comiected to the valve 8 and extends into thereservoir 6.

The cyindrical chamber or valve 8 is of smaller exterior diameter thanthe internal diameter of the cylinder or valve 9. The valve 8 extendsthrough the rear wall of the valve 9 and is suitably secured therein.The forward wall of the' valve 9 is provided with a vertical slit II.The horizontal slit 12 in the valve 8 and the vertical slit II in thevalve 9 are positioned with respect to each other in a manner to form arightangle to provide a pump and ejector assembly which operates in amanner hereinafter described.

The pump and ejector assembly consisting of the valves 8 and 9 is placedwithin the muzzle 4 of the pistol in a position between the anvil ll anda trigger 5. The trigger 5 is pivotally carried upon the frame by meansof the pivot pin [8. The pivot pin H) for the trigger 5 is positionedsubstantially forwardly of the main arm of the trigger 5 so that a leveraction is provided by the rear end of the trigger 5.

The pump and ejector assembly is placed between the anvil I! and thetrigger 5 so that the forward end of the rear valve 8 is positionedadjacent and between the anvil l1 and the trigger 5. The slit l2 in therear valve 8 is arranged parallel to the bottom surface of the anvil I7.The slit II in the valve 9 is thus arranged normal to the bottom surfaceof the anvil I1 and to the slit I2 in the valve 8.

When the trigger 5 is pulled rearwardly the wall of the valve 9 iscompressed to collapse upon the forward end of the valve 8. Since theslit I2 in the valve 8 is parallel with the bottom surface of the anvilll the slit will be pressed together to prevent fluid within the valve 9from returning to the reservoir 6. The upward and forward compression ofthe valve 9 by the trigger 5 opens the slit ll therein to permit wateror other fluid to be ejected through the slit ll. When the trigger 5 isreleased the slit II in the valve 9 will immediately close due to therelease of hydraulic pressure within the valve 9. When the slit l lcloses and the valve 9 is permitted to reexpand to its normal size asuction or vacuum will be created within the valve 9. When the walls ofthe valve 9 have removed pressure from the forward end of the valve 8the suction within the valve 9 will draw fluid through the tube 1 andthe slit l2 into the hollow body of the valve 9.

The forward ends of the valves 8 and 9 are shaped arcuately. so that ineffect the slits therein provide a one Way valve action. Any-pressureupon the external periphery of either of the valves 8 or 9 tends to sealthe slits I 2 and II respectively.

In this invention the pistol consists of a frame I, having a liquidreservoir 6, together with operating mechanism for means for ejectingfluid from the pistol. The operating mechanism chamber which is locatedin the forward part of the pistol frame terminates in the muzzle 4 ofthe pistol. A fill opening is provided in a cap or cover 3 located inthe top of the pistol frame, said opening being closed by means of aremovable stopper 2 which has a V out in the top edge thereof to providea rear sight for the pistol. An anvil I! is positioned inside of andadjacent the upper wall of the frame I in the muzzle portion of thepistol. A front sight [I] is positioned on the forward end of the muzzle4.

I claim:

A water pistol comprising a frame, a fluid reservoir therein, anejector, said ejector comprising a collapsible chamber having a slit inone end thereof closed by the normal position of said chamber andforming a valve therein, a second valve positioned within said ejectorformed by a collapsible chamber having a slit therein arranged normal tothe first mentioned slit, means connecting said second mentioned chamberwith the fluid reservoir, and means for collapsing said first mentionedchamber parallel with the plane of the slit in the second mentionedchamber to eject fluid through the first mentioned slit.
